    “Boyd’s Black-Haired Bug”

    Robert S. Boyd is Alumni Professor in the Department of Biological Sciences at Auburn University, Alabama.

    He received his doctorate in Botany from the University of California, Davis in 1986, and a master’s and undergraduate degree from Cal Poly Pomona. He is currently teaching conservation biology and has taught botany and ecology at Auburn University since 1988. His research interests include the management of rare and endangered plants, as well as the ecology and evolution of metal “hyperaccumulator” plants. These are plants that take unusually large amounts of metals into their tissues. In fact, Bob has had an insect species, “Boyd’s Black-Haired Bug” (Melanotrichus boydi) named after him for his work in this area. The bug feeds on the milkwort jewelflower (Streptanthus polygaloides), a nickel hyperaccumulator endemic to the Sierra Nevada.

Volunteer at the Hoover Herbarium

During the volunteer sessions at the Hoover Herbarium, people can take part in any number of activities.  One of our primary responsibilities is mounting new specimens.  This involves taking dried and pressed plants and glueing them to paper.  When we mount plants, we do it in such a way that those specimens will last for hundreds of years.  Each specimen is a physical record of what plants occurred where and when.  Without this valuable information we wouldn’t know when a species goes extinct, expands or contracts its range, or where species occur.  After mounting, the specimens are databased and geo-referenced.  Then they are filed into the main collection. We have over 80,000 specimens at the Hoover Herbarium.  We are also working on a SLO Voucher Collection, which will contain one representative specimen for each species in the county.  Volunteers look through our specimens and pick the one that should be added to the Voucher Collection.  Additionally, we are actively working on our moss and lichen collections.  Volunteers can choose what aspects of the work they would like to participate in.  Any and everyone is welcome. The Hoover Herbarium is located on the 3rd floor of the Fisher Science Building (33) in rooms 352 and 359.

Starting Sept 18th, the herbarium volunteers sessions will be Mondays from 3-5 pm and Fridays 9 – 1.
Parking permits are required on campus Monday through Thursday, 7:00 am through 10:00 pm; and Friday, 7:00 am through 5:00 pm. You can either buy a $6 day pass, a $4 3-hr pass, park in a metered space, ride the bus, or park off campus and walk in.  Questions: email Jenn Yost at jyost@calpoly.edu
